Title: Improvements in or relating to the electrolytic production of titanium
Inventor: QUIN JAMES PATERSON
IPC: C25C3/28
Filed: 1955-06-24
Abstract: Titanium nitride is produced by heating finely-ground ilmenite or rutile mixed with powdered carbon at a temperature in excess of 1000 DEG  C. in an atmosphere of nitrogen.  Iron impurities may be partially removed by magnetic means and the remaining iron and other impurities are removed by treatment with dilute acid. Titanium trichloride is produced by passing a mixture of titanium tetrachloride and hydrogen through molten potassium chloride at 850 DEG  C., the trichloride remaining in solution in the melt and the hydrogen chloride simultaneously formed passing off.ALSO:To make an anode for use in the production of titanium by fused salt electrolysis, finely milled titanium nitride is compacted at a pressure of 10 tons/sq. in. and is then sintered for two hours at a temperature exceeding 1500 DEG C. in an atmosphere of nitrogen. Finely divided titanium may be added to the nitride as a binding agent.  The nitride anode may have an atomic N/Ti ratio not less than 0.9.

Patent GB-357143-A (GB)
Title: Improvements in and relating to television and the like
IPC: H04N3/34
Filed: 1930-06-16
Abstract: 357,143. Converting ; changing wave form. HARRIES, J. H. O., Shirley, Old Road, Frinton-on-Sea. June 16, 1930, No. 18358. [Class 38 (ii).] A potential, for use in television apparatus, of the wave form shown in Fig. 1 (y =a sin w - <a>/3sin 3w), is produced by two generators 3, 4, Fig. 3, delivering wave forms y=a sin w and y=<a>/3 sin 3w respectively. The two wave forms are combined 180 out of phase at 6 and the potentiometer 5 may be further varied to alter the combined wave form. This wave form may also be produced by the apparatus of Fig. 4 in which a resistance 14 is periodically varied by movement of the contact arm 11 governed by a rotating cam 10. Alternatively, the grid bias of a pair of triode valves in push-pull arrangement may be such that the lower values of a sine wave impressed on the grids are partially suppressed, the peaks being produced normally. The wave form 2, Fig. 2, may be produced by the apparatus of Fig. 5, in which a disc 15, carrying a wire 16, is uniformly rotated against a stationary contact 18 completing a circuit through a transformer. The resulting periodic variation of the circuit resistance is lowered when the contact 18 passes over the junction of a shunt 19 with the wire 16. Alternatively the condenser 21, Fig. 6, may be charged to a potential having a wave form of the curve 2, Fig. 2, from a condenser 20 charged by a battery 27 through the diode 25. When the voltage reaches the point x on the curve 2, Fig. 2, the effect of the biasing battery 24 is overcome and the diode 23 becomes conducting, shunting the condenser 20 and reducing its rate of charging until the point y, Fig. 2, is reached. At this point, the voltage on the condenser 20 overcomes the biasing battery 29 and the triode 26 becomes conducting, thus increasing the charging current on condenser 20. The condenser 20 is periodically discharged by a relay 22. Specification 328,680, [Class 38 (ii), Electric currents, Converting &c.], is referred to.
Patent GB-516530-A (GB)
Title: Improvements in or relating to electric circuit-breaking devices of the gas-blast type
IPC: H01H33/98
Filed: 1938-06-21
Abstract: 516,530. Gas-blast switches. REYROLLE & CO., Ltd., A., COATES, F., LEESON, B. H., and ALLAN, A. June 21, 1938, No. 18387. [Class 38 (v)] An air or gas - blast circuit - breaker has the arc formed within an enclosure having on one side only in the wall thereof one or more lateral discharge vents past which the arc is drawn, and the blast is derived from a source external to the enclosure and forced through the arc path and out of the enclosure through the vents, the blast-supply to the enclosure being controlled by a valve member which is constituted by one of the relatively-movable contacts or by a part associated therewith. The gas may be air, nitrogen, carbon dioxide, argon, or a gaseous fluorinated alkyl chloride such as dichloro - difluoro - methane.. The invention is described and illustrated in Figs. 1-8 (not shown), in its application to certain Figs. of Specifications 516,529 and 516531, the arrangement of Fig. 1 (not shown) including also a plug associated with the arcing structure and filling the tip of the hollow movable contact in the closed position so as to free the blast near the beginning of the opening movement. Specification 516,532 is also referred to. The arcing enclosure of Fig. 9 has vents K' and aligned inlet ports K<2> supplied by pipe G<3>, the ports being successively uncovered by a spring-controlled valve K<3> which is normally held closed by a projection K' on the movable contact C. Fig. 10 shows an arrangement for withdrawing the movable contact C into clean gas in the open position, by placing a plate M across the container D so as to leave a clean-gas space M<1> below it. The gas reservoir F<3> contains contactactuating mechanism, the operation of which. before the contact actually moves, opens a valve M<2> by means of the system M'... M<6>. Thus the container D may all be filled with compressed gas while the switch is closed, the valve allowing the discharge side to exhaust and the blast to be set up before the contact moves, so obviating the need for perfect gastight closure of the vents B<4>. At the end of the opening stroke, pressure is again restored by closure of the valve. Where a solid contact C and separate gaspipe are used, the valve is placed in the latter, and the compartment M<1> mav contain insulating liquid. Alternatively or additionally, a series-break M', M<9> may occur in timed relation to the main break and in a gas or liquid-filled casing M'. The Specification also refers to an arrangement which is similar to that of Figs. 7, 8 of Specification 516,529. The rod-contact may be kept fixed and circuit opened by movement of the arcing enclosure.

Abstract: 515,341. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., and BOURNE, S. N. June 21, 1938, No. 18449. [Class 38 (v)] A protective system for a two- or three-phase motor comprises the provision of voltage relays for determining whether the conditions are suitable for connecting the motor to the line, and preventing connection unless all phases of the line are energized, and series coil relays for disconnecting the motor if one phase becomes opencircuited while the motor is running. The invention is applicable to motors which are started automatically by means of tappet, float, or compressor switches. The supply L<1> ... L<3> is adapted to be connected to the motor terminals A ... C by a contactor 1, the closing coil K of which is energized, on closure of switch P, only if all the star connected voltage - relay coils D ... F are energized and their contacts d ... f thereby closed. Relay coils L ... N in the lines thereupon close their contacts l ... n and are adapted to maintain them closed with the minimum (magnetizing) line-current. If a line is opencircuited, the corresponding contact l, or m, or n opens and introduces into the circuit of coil K a heater H which, after a time-delay, opens the contact of a relay G and de-energizes the coil F. Contact f thereupon opens and de-energizes the coil K, so opening the contactor 1. The contacts of relay G are adapted to be latched open and reset manually or by a remote-controlled coil.
